Select which columns from CSV to graph with HighChart - csv

Question

As I was looking at the question How do I select which columns from my CSV to chart with HighChart? I tried to apply it using a csv file but I could not get it to work!
What am I doing wrong? Thank you in advance:
$(function () {
//var data = "Year,Month,Day,Hour,Time,kWh,Savings,Total kWh\n2013,02,06,11,11:00,0,0,308135\n2013,02,06,11,11:59,15,1.875,308150\n2013,02,06,12,12:59,27,3.375,308177\n2013,02,06,13,13:59,34,4.25,308211\n2013,02,06,14,14:59,32,4,308243";
var options = {
chart: {
renderTo: 'EXAMPLE',
defaultSeriesType: 'line'
},
title: {
text: 'Current Temperature',
x: -20 //center
},
subtitle: {
text: 'Source: hassayampa.csv',
x: -20
},
xAxis: {
type: 'datetime'
},
yAxis:{
title: {
text: 'Temperature (\xB0C)'
},
//min: 0
},
legend:{
layout: 'vertical',
//backgroundColor: '#FFFFFF',
//floating: true,
align: 'left',
//x: 100,
verticalAlign: 'top',
//y: 70,
borderWidth: 0
},
series: [{
name: 'PRIM OUT TEMP',
data: []
}, {
name: 'SEC OUT TEMP',
data: []
}]
};
// data is variable from $.get()
$.get('http://www.geoinc.org/Dropbox/geo/sites/GC_ROOM/EXAMPLE.csv', function(data){
var lines = data.split('\n');
$.each(lines, function (lineNo, line) {
var items = line.split(',');
if(lineNo !== 0) {
var x = + new Date(items[1]+'/'+items[2]+'/'+items[0]+' '+items[4]),
kwh = parseFloat(items[5]),
savings = parseFloat(items[6]);
if(!isNaN(kwh) && !isNaN(savings)){
options.series[0].data.push([x,kwh]);
options.series[1].data.push([x,savings])
}
}
});
});
new Highcharts.Chart(options);
});

I got it now...
// data is variable from $.get()
$.get('http://www.geoinc.org/Dropbox/geo/sites/GC_ROOM/EXAMPLE.csv', function(data){
// parsing here...
});
new Highcharts.Chart(options);
});
Your problem is the placement of the new Highcharts.Chart(options) call. $.get (like most ajax calls) is asynchronous So the new Highcharts will be called before it completes.
Change it to this:
// data is variable from $.get()
$.get('http://www.geoinc.org/Dropbox/geo/sites/GC_ROOM/EXAMPLE.csv', function(data){
var lines = data.split('\n');
$.each(lines, function (lineNo, line) {
var items = line.split(',');
if(lineNo !== 0) {
var x = + new Date(items[1]+'/'+items[2]+'/'+items[0]+' '+items[4]),
kwh = parseFloat(items[5]),
savings = parseFloat(items[6]);
if(!isNaN(kwh) && !isNaN(savings)){
options.series[0].data.push([x,kwh]);
options.series[1].data.push([x,savings])
}
}
});
new Highcharts.Chart(options); // this is now in the $.get callback function
});
